Mana

The health bar, colored green, on top, and the Mana bar, colored blue, on the bottom.

Mana is the resource of some champions necessary to cast most of his/her abilities. The mana pool is represented by a blue bar below the green health bar and two numbers ( # / # ) in the middle of it. The first one is your current amount of mana and the second refers to the maximum amount you can store. Mana regenerates over time and this rate can be increased with masteries and items.

Mana Surge restore 30-195 (27 + 3 / 6 / 9 / 12 / 15) mana every 12 seconds on a basic attack. The amount of mana restored is doubled if the attack target is a champion. This does not apply to structures.

Increasing mana

Several items and runes can increase the total mana of a champion. This statistic scales additively, which means that each bonus point acquired is directly added to the mana pool.
